Abstract
Abstract A working combination of a stapler assembly (10) for fastening together sheets of paper or the like with U-shaped wire staples (S) one at a time and a punch assembly (12) capable of simultaneously perforating two holes. The stapler assembly is per se of conventional make including an elongate base (14) carrying a matrix (16) against which successive staples are forced out of a staple magazine (18) by a handle (20) having an ejector (22). The punch assembly comprises a platen (50) permanently or removably fastened to the stapler base, and a bed (54) hingedly coupled to the platen for relative pivotal motion about an axis extending longitudinally of the stapler base. A pair of perforating punches (52) are formed on either of the platen and the bed, and bores (58) for receiving the punches are formed in a die or dies (56) mounted to the other of the platen and the bed.
